Specifically, FIG. 14 is a block diagram illustrating the construction of a control unit of the water facility according to the invention, and FIG. 15 is a flowchart illustrating a process of controlling the water facility according to the invention.

As shown in FIGS. 1 to 16, the water facility A according to the invention includes floating bodies 10 and 10′ floating on the surface of the water 2, a walking stage 20 placed below and connected to both the floating bodies 10 and 10′, thereby forming a footing, and rails 30 and 30′ connecting each edge of the walking stage 20 with a corresponding one of the floating bodies 10 and 10′.

With this construction, the water facility A can be installed in the seashore, riverside or lakeside to be partially immersed into the water, in a place apart from the shore when an anchor is installed, or in the middle of a calm lake. Accordingly, the walking stage 20 is supported by the floating bodies 10 and 10′ to be placed in the water below the surface of the water.

The water facility A including the walking stage 20, the floating bodies 10 and 10′ and the rails 30 and 30′ can be installed in the riverside or lakeside as a small facility, with one side extending merely several meters. The water facility A can also be installed in the edge of a great lake and a river, or even in the edge of a small seashore when one side is several tens of meters. Furthermore, the water facility can be installed in the edge of a great seashore when it has a large size with one side extending from 100 to several hundred meters.

Especially, in the case where the water facility is installed with a large size in the great seashore, the walking stage 20, the floating bodies 10 and 10′ and the rails 30 and 30′ can be installed more stable so as to withstand waves, or even to support not only users but also a wheelchair, a powered wheelchair, a cart and so on. A monitoring system can be constructed to ensure safety, and a device such as a marine anchor can also be installed. Of course, safety facilities can be installed and lifeguards can be arranged in places to ensure the safety of users, and a structure with a warning sign can be installed either.

The walking stage 20 immersed below the surface of water can be immersed at a depth where an adult can safely walk, which is about one (1) meter. When the walking stage 20 is designed for children, its depth is designed to be rather shallow. Preferably, the dept can be about 50 cm.

The walking stage 20 can be constructed with a net having dense meshes or a bar-shaped assembly in which round bars or rectangular bars connected in parallel with each other at a small interval. This construction allows water to freely pass through a number of openings so that the walking stage 20 can stably maintain its shape.

The walking stage 20 can be constructed with plates on which people can easily walk on the top surface of walking stage 20, immersed in the water. Furthermore, the wheelchair, powered wheelchair or cart can move on the plates of the walking stage 20. In this case, the wheelchair, powered wheelchair or card can preferably have corrosion resistance against the sea water or moisture. In the walking stage 20 constructed with plates, each plate is rectangular shaped with a length approximately from 1 to 5 m and a width approximately from 20 cm to several meters. However, this is not intended to limit the invention. It is apparent that the invention can adopt other lengths, widths, thicknesses and shapes to ensure structural stability and use a variety of materials in more various manners. In addition, the shape is not limited to the rectangular shape but can include other various forms considering installation stability and material. Available shapes may include an arc, a portion of ellipse, a triangle, a polygon, various other shapes each reminding a specific character, and so on.

In the case where the walking stage 20 is constructed with plates, it may have a single layer structure as shown in FIGS. 7 and 8, or a multiple-layer structure as shown in FIG. 6. In the case of the single-layer structure, respective plates are fixed to a plurality of posts 31 of the rails 30 and 31′ and are connected to each other by connecting means such as ropes and wires. In the case of the multiple-layer structure, upper layer plates and lower layer plates are fixed to respective posts 31 in a staggered fashion. Specifically, each of the upper layer plates is fixed at opposite edges thereof to corresponding posts and each of the lower layer plates is fixed at opposite edges thereof to corresponding posts, such that the leading edge of one upper layer plate is either ahead of or behind the leading edge of an adjacent lower layer plate. The walking stage 20 can be constructed in other various methods and forms, and is not limited to the above-described forms.

In the water facility A according to the invention as shown in FIGS. 2 to 8, the floating bodies 10 and 10′ can be formed of foam resin or be constructed with buoyant members, each of which has an air-containing space 111 therein.

The buoyancy of the floating bodies 10 and 10′ allows the walking stage 20 and the rails 30 to remain at a predetermined depth in the water without sinking into the water.

In the case where each of the floating bodies 10 and 10′ is constructed with a case 11 and the space 111, the floating body can be equipped with a moisture sensor w therein. The moisture sensor w is designed to detect moisture infiltration into the space 111 when the case 11 is fractured or cracked by an external force. The moisture sensor w can be implemented with a typical moisture sensor. Since a current value, an optical feature and so on measured by the moisture sensor w in the absence of moisture are different from those measured by the moisture sensor w in the presence of moisture, it is possible to determine moisture infiltration based on these differences.

As shown in the figures, the floating bodies 10 and 10′ are constructed to enclose the water facility A of the invention. The floating bodies 10 and 10′ serve to stably hold the entire structure of the water facility A so as not to lose its shape.

For this purpose, inside members such as safety connectors 13 are equipped inside the floating bodies 10 and 10′. The safety connectors 13 can be made of iron rods, metal rods, alloy rods and so on, or be constructed with wire ropes consisting of several metal strands twisted together. In addition, a plurality of the safety connectors 13 can be constructed together. As shown in FIG. 2, ends of the safety connectors 13 can be bound to fixing rods 4, which are fixed to the ground 3. Accordingly, the water facility A of the invention can maintain a stable position irrespective of waves and the flow and ebb since it is fixed by the fixing rods 4 as well as an anchor.

As shown in FIGS. 2 and 4, the floating bodies 10 and 10′ are constructed to enclose the entire length of the safety connectors 13 at a uniform thickness. The cross-sectional shape the floating bodies 10 and 10′ may include a circle, a quadrangle, a polygon and so on. As shown in FIG. 3, the floating bodies 10 and 10′ can be constructed with a plurality of small individual outer bodies, which are connected to each other to enclose the safety connectors 13. In particular, the individual outer bodies enclosing the safety connectors 13 can be constructed to be easily engaged with and disengaged from each other. Not only the floating bodies 10 and 10′ but also the walking stage 20 and the rails 30 and 30′ can be constructed to be disassembled, and the water facility A of the invention can be installed on the water when it is used but be stored in a disassembled state when it is not used. Accordingly, the water facility A of the invention can be conveniently used.

Furthermore, as shown in FIG. 3, when the entire shape of the water facility A is quadrangular, triangular or polygonal, the floating bodies 10 and 10′, the walking stage and the rails 30 and 30′ in each side can be constructed with individual members. In this case, the individual members can be assembled to each other when they are used, but be disassembled from each other when they are stored or moved. With this construction, the water facility A of the invention can be more conveniently used.

In addition, the floating bodies 10 and 10′ are equipped with knobs 12 and 12′. As shown in FIGS. 5, 7 and 8, a user can easily walk in the water while holding the knobs 12 and 12′ with hands. Since the head, upper body and arms of the user are placed above the surface of the water 2 but the lower body and legs are immersed in the water, the user can walk on the walking stage 20 in the water while holding the knobs 12 and 12′ on the surface of the water.

The rails 30 and 30′ can be constructed with a net or a plate having a plurality of holes such that waves, the flow and ebb or running water of the river can easily pass through the holes of the net or plate body. The rails 30 and 30′ are constructed with a plurality of the posts 31, by which the floating bodies 10 and 10′ support the walking stage 20. The posts 31 of the rails 30 and 30′ connect a marine device such as an anchor to the floating bodies 10 and 10′, thereby generating a fixing force to more stably maintain the entire structure of the water facility A.

When the weight of the floating bodies 10 and 10′, the walking stage 20 and the rails 30 and 30′ cause the water facility A to be heavier, buoyant members can be added to corresponding places. The buoyant members can be formed of foam such as Styrofoam, or be constructed with a tube containing air or gas.

As shown in FIG. 4, the water facility A of the invention can be provided with safety zones 15 for lifeguards. The safety zones 15 can be fixed to the rails 30 and 30′ or the floating bodies 10 and 10′, or be constructed with a foam member or tube.

The water facility A of the invention as described above can be constructed in a variety of shapes as shown in FIGS. 9 to 14.

For example, the water facility can be constructed in a quadrangular shape with one open side a semi-elliptical shape and a semicircular shape as shown in FIGS. 9 to 11, or be constructed in a closed shape such as a polygonal shape, an elliptical shape and a circular shape as shown in FIGS. 12 to 14.

When the water facility is constructed in the quadrangular shape with one open side as shown in FIGS. 9 to 11, the open side can serve as an entrance through which users can enter and exit the water facility through the entrance. When the water facility is not open as shown in FIGS. 12 to 14, an entrance 16 can be installed in one side.

The water facility A of the invention can be fixedly installed in the seashore, riverside and the like. In this case, the entrance is constructed to contact the ground 3, but other parts are placed on the surface of the water or in the water. As described above, as the user walks on the walking stage 20 while holding the knobs 12 and 12 with hands, his/her body is gradually immersed in water.

When users are completely on the water facility A, it can be safely towed to an area apart from the seashore at a distance of about several, several tens of or several hundred meters, and be fixed in position so that the users can enjoy a variety of water activities on the sea.

For this, one or more towing connectors (not shown) can be installed on the water facility A. As shown in FIG. 12, projectors 22 can be installed on opposite sides, and a main control unit 40 can be installed on one side to operate the projectors 22.

As shown in FIGS. 4 and 5, level areas 25 can be provided inside the water facility A of the invention. In the level areas 25, the users can swim or enjoy other water activities.

Level plates 254 are provided at the bottom of the level areas 25. Even if the water facility A of the invention is placed in a deep water area, the users can safely swim in the water above the plates 254. The level areas 25 can be divided into a first level area 251 with a depth of about 1 m, allowing adults to swim therein, and a second level area 252 with a depth of about 50 cm, allowing children to swim therein.

In addition, buoyant members 253 can also be provided adjacent to the level plates 254 in order to support the weight of many users. The buoyant members 253 can be constructed with foam or a tube containing gas. In addition, under the control of the main control unit 40, gas can be supplied to or removed from a corresponding one of the buoyant members 253 supporting the level plates 254 or the buoyant members supporting the walking stage 20 in order to cope with the varying weight in response to change in the number of users. This as a result allows the walking stage 20 and the level plates 254 to remain in a predetermined depth. For this, an air pump, an air compressor tank, air pipes, sensors and the like can also be provided.

The main control unit 40 can be constructed to control the water facility A of the invention according to its safe and emergency situations.

As shown in FIG. 15, the main control unit 40 includes a safety inspection signal-processing block 42, an emergency signal-processing block 43, an input/output signal-processing block 44 and a main controller 41 for controlling parts of the water facility A.

A structure safety sensor unit 50 is installed on one or more places of the floating bodies 10 and 10′, the rails 30 and 30′ and the walking stage 20 to detect whether or not any of the floating bodies 10 and 10′, the rails 30 and 30′ and the walking stage 20 is damaged. The structure safety sensor unit 50 is connected to the main controller 40, which determines the state of the floating bodies 10 and 10′, the rails 30 and 30′ and the walking stage 20.

The structure safety sensor unit 50 can include a safety loop 51, which is continuously placed around the floating bodies 10 and 10′, the rails 30 and 30′ and the walking stages 20 in a continuously-surrounding shape.

The safety loop 51 can be constructed as a loop sensor, which can transmit and receive supersonic waves or optical signals. The loop sensor can carry out a communication method, which can be performed by a typical loop sensor. Specifically, the safety loop 51 transmits signals from signal transmitters (not shown) at both portions thereof. When the signals are properly received from the counterpart transmitters, the main control unit 40 determines the safety loop 51 to be in a normal state without a damage in a circuit. However, when the signals are not received from the counterpart transmitters, the main control unit 40 determines the safety loop 51 to be in an abnormal state. In this case, each of the transmitters receives its own signal, and a cut portion can be located by analyzing the received supersonic or optical signal.

The safety loop 51 can be provided with point sensors d, which are arranged at an interval of several tens of centimeters, several meters or several tens of meters. Accordingly, when the signals are not received, a cut portion is found by locating a particular point sensor d, which is detected from both parts.

In addition, the structure safety sensor unit 50 can include the moisture sensor w, which is provided inside the space 111 of the floating bodies 10 an 10′ as shown in FIG. 8. The point sensors d and the safety loop 51 can be provided to determine any damage of the floating bodies 10 and 10′, the walking stage 20 and the rails 30 and 30′. In addition, the moisture sensors w detect moisture infiltration into the floating bodies 10 and 10′ in response to cracking or fracture of the exterior of the floating bodies 10 and 10′. The moisture sensors w can determine in advance whether or the floating bodies 10 and 10′ are damaged in the state where the safety connectors 13, which securely connect the entire structure, are not damaged.

Furthermore, emergency buttons s for generating an emergency signal can be installed in a plurality of places, such as the knobs 12 and 12′, the floating bodies 10 and 10′, the safety zones 15, the level areas 25 and so on. Accordingly, when a user notices an emergency situation while he/she is walking on the walking stage 20 or is swimming or playing a water activity in the level area 25, the user can push the emergency button s to warn the emergency situation. Examples of the emergency situation may include an emergent patient, an accident, a damage of the water facility A and the like.

The structure safety sensor unit 50 including the safety loop 51, the point sensors d, the moisture sensors w and the emergency buttons s can be constructed with one circuit or a plurality of individual circuits. The circuits of the structure safety sensor unit 50 can be installed in the floating bodies 10 and 10′, respectively, and be installed in both edges of the walking stage 20, respectively. Alternatively, a separate circuit can be installed in each part.

A signal from the structure safety sensor unit 50 is transmitted through the safety inspection signal-processing block 42 of the main control unit 40. Accordingly, the main control unit 40 connected with the structure safety sensor unit 50 determines whether or not the signal from the safety inspection signal-processing block 42 informs an emergency situation.

In the case of a normal signal, the main control unit 40 waits for the next signal. However, in the case where the emergency situation is determined based on a damage in the floating bodies 10 and 10′, the walking stage 20 or the rails 30 and 30′, the main control unit 40 sends an emergency signal through the emergency signal-processing block 43 to an emergency light 52 or a speaker 53.

The input/output signal-processing block 44 transmits the emergency signal associated with the emergency situation to an external organization via an input/output terminal 441. Examples of the external organization may include a control office in charge of seashore facilities; and a rescue team, a police station, a hospital and a fire station, which are ready for an accident in the water facility A or the seashore.

The water facility A of the invention constructed as above can be controlled according to the following steps.

1) Firstly, the water facility A including the floating bodies 10 and 10′, the walking stage 20 and the rails 30 and 30′ is installed on the water and the structure safety sensor unit 50 is installed on the water facility in connection with the main control unit 40 to be ready for the operation of the water facility (facility operation preparing step S01). The water facility A can optionally include the level areas 25, the safety zones 15, the emergency light 52, the speaker 53, the projectors 22 and an air supply. In addition, a searchlight 54 for lighting nighttime facilities and a searchlight block 45 for operating the searchlight 54 can be provided.

The facility operation preparing step S01 includes receiving normal initial values from the sensors connected to the floating bodies 10 and 10′, the walking stage 20, the rails 30 and 30′ and other members and storing the normal initial values in a memory 401, so that an abnormal emergency state can be determined based on the initial values. In the case of the safety loop 51 of the structure safety sensor unit 50, an initial value is set based on whether or not signals from the both transmitters are properly received. In the case of the point sensors d, an initial value is set based on whether or not a response signal from an individual sensor is properly received. Furthermore, in the case of the moisture sensors w, a value measured in the absence of moisture is set as an initial value, and a value measured in the presence of moisture is set as an initial value. Here, the initial value is measured from sea water in the case of sea and from fresh water in the case of river or lake.

In the case of the emergency button s, since an emergency signal is received when the emergency button s is pushed, an initial value is set by measuring the state where the button is not pushed. In the case of other parts, initial values are measured from the corresponding parts at the time of installation before the parts are used. These initial values are stored in the memory 401.

2) The water facility A is operated, and a signal sent from the structure safety sensor unit 50 is received via the safety inspection signal-processing block 42 (sensor signal receiving step S02).

3) The signal received via the safety inspection signal-processing block 42 is determined whether or not to be a normal or emergency signal (sensor signal determining step S03), and based on the result, the water facility A is determined whether or not it is normally operating.

4) If the signal is determined as an emergency signal in the sensor signal determining step S03, the emergency signal is transmitted to the emergency signal-processing block 43 to warn an emergency situation using the emergency light 52 and the speaker 53 (emergency signal generating step S04). The emergency light 52 and the speaker 53 allow users to be prepared for the emergency situation and lifeguards to properly cope with the emergency situation.

In addition, under the control of the main control unit 40, the emergency signal is also sent to an external organization, such as a police station, a fire station and a hospital, and a control office in charge of the seashore facilities, which are connected to the input/output terminal 441. In this manner, the emergency situation can be properly handled.
